AUTOMATBC FEEDlNG DEVICE-FOR ROLLER WHLLS.

'JPECIPICATION forming part of Letters Patent No. 306,365, dated October7, 188%.

Application filed June 16, 1884. (No model.)

To aZZ whom it may concern.-

Be it known that I, MONROE l3. Tiri owga citizen of the United States,and residing in Treiehler, Northampton county, State of Pennsylvania,have invented certainImprovements in Automatic Feeding Devices forRoller- Mills, of which the following is a specification.

The object of my invention is to construct an automatic.feed-regulatorof such a character that it can be readily applied to the hoppers ofroller-mills as 110w constructed, and

this object I attain in the manner hereinafter set forth, referencebeing had to -the accompanying drawings, in which Figure l is atransverse section of sufficient of a roller-mill hopper and casing toillustrate my invention; and Fig. 2, a longitudinal section on the line1 2, Fig. 1, some of the parts being shown in elevation.

A is the casing of the mill; B, the hopper, D, the usual feed-roll, andF the valve, which, in conjunction with the roll D, serves to regulatethe feed of the grain from the hopper to the rollers in the casing A.This valve F is suspended by rods a a from levers G G, hung by pins Z)to a box, H, secured to the outside of the hopper-casing, the rods beingacted upon by springs (l, hung to pins 6 on the box,

and the tension of these springs being regulated by the adjustment ofnuts f, guided by lugs g on the box, and adapted to the threadedportions of the screw-stems h, which have collars t, whereby they arevertically confined to bearings in the top of the box, so that byturning the stems the nuts will be raised or lowered. Each lever hasformed in it a slot, at, and to these slots is adapted the short arm ofa lever, J, which is pivoted to a block, a, inside of the hopper, saidshort arm of the lever projecting through an opening, 1), in thehopper-casing, and the long arm of the lever extending into thehopper,and being furnished with a float, K. This float rests upon the 5 mass ofgrain in the hopper, and as the level of the grain falls the levers G Gwill be operated so as to raise the valve F to an extent proportionateto the decreased pressure of grain thereupon, a uniform feed being thusautomatically maintained.

It will be observed, on reference to Fig. 2, that the lever G is shorterthan the lever G, so that the lever J may be placed at one side of thecenter of the hopper, and thus not inter fere with the usual automaticshut-cit mechanism with which the valves of most rollermills areprovided, and which is arranged centrally in the hopper. The rods (0 aare so connected to the levers in respect to the fulcrums of the latter,however, that the lift of 6c the valve will be uniform.

.t will be observedthat all of the regulating devices, with theexception of the lever J, are carried by the box H, which can be readilysecured in posit-ion on the casing A by 6 5 an ordinary mill-handwithout the aid of a carpenter, the only cutting of the casing which isnecessary being the formation of the opening 1) for the lever J and theopenin q for the rods a a.

The valve F is not radially in line with the center of the feedroll D,but is a little on one side of the center of the roll, as shown in Fig.1, this location enabling me to feed coarse grain with greater facilitythan when the valve 7 5 is directlyin line radially with the center ofthe feed-roll.

I claim as my invention?- 1. The combination of the hopper, feed-roll,and valve of a roller-mill, with a lever, J, extending into the hopperand carrying a float,

K, a pair of levers, G G, engaging with the short arm of the lever J,and rods (0 a, where by said levers G G are connected to the valve, asset forth. j

2. The combination of thehopper, feed-roll, and valve, the lever J,having float K, thele vers G G, connecting-rods a a, springs (Z (Z, nutsf, and screw-stems h, as specified.

3. The combination of the hopper, feed-roll, and valve, with the leverJ, having float K, and the levers G. G, connected to the valve,

and of different lengths, as described, where- In testimony whereof Ihave signed niynalne by the lever J is arranged at one side of the tothis specification in the presence of two snbcenter of the hopper, asset forth. scribing witnesses.

4. The combination of the casing A, hopper, feed-roll, valve F, andlever J, having MONROE B. TITLOW'. float K, with regulating devicesconnected to the valve F and lever J, and a box, H, de W'itnesses:tachably secured to the outside of the casing D. L. HAMAKER, A, asspecified. HENRY T. KLncKNnn.
